The Indian Forester August 1933

1933

In the course of the preceding articles surveying the position of silvicultural research in Europe frequent reference has been made to the statistical analysis of experimental results and to the adoption of special methods in laying out experiments such that the data collected would lend themselves to some determination of the errors involved. [...] The exhaustion of oxygen and accumulation of CO2 in the soil is believed to be largely due to the action of the organisms engaged in disintegrating and breaking down the soil humus and organic matter and we should therefore naturally expect the damage from bad soiaeration to be most marked in regions of heavy rainfall and warm climate and in the case of evergreen species which keep the soil c [...] On the other hand owing to the large proportion of mulberry in the plantation the soil is well shaded by the heavy foliage when the trees are in leaf and there is a considerable addition of humus to the surface soil while soil-aeration is also probably adversely affected by the plugging of the surface with a deposition of silt under the irrigation system of surface-flooding. [...] Other probably adverse factors are the wounding of the roots in the work of clearing the irrigation channels and the probable assistance rendered to the fungus by the irrigation water in the way of distributing its spores. [...] The true remedy for the disease of sissoo in this case appears in fact to lie rather in more adequate consideration being paid to the vital needs of the tree in respect of water and air than in a campaign directed against Fomes lucidus.1933 ] PLANT PATHOLOGY IN THE FORESTS OF INDIA If the view here taken is correct that the factor of primary impotance is a sickly condition of the tree induced
